       2. The plant of claim  1  wherein said flowers have outer five parted corolla limbs and inner five parted petaloids, said petaloids overlaying the corolla limbs. 
     
     
       3. The plant of claim  1  wherein said flowers have outer five parted corolla limbs and inner five parted petaloids, said petaloids being shorter than the corolla and remaining in a cluster within outer corolla, forming a tight cluster habit of petaloids generally prohibiting a view of the inner throat. 
     
     
       4. A plant structure derived from the plant of claim  1 . 
     
     
       5. A plant produced by propagating the Mandevilla variety ‘Rita Marie Green’ of claim  2 . 
     
     
       6. A Mandevilla variety essentially derived from the plant of claim  1 , wherein the essentially derived plant displays at least one double flower. 
     
     
       7. A plant part from the plant of claim  1 . 
     
     
       8. Plant material from a plant of claim  1  which is capable of reproducing a double flowering Mandevilla plant. 
     
     
       9. A method of producing a double-flowering Mandevilla plant comprising propagating a double-flowering Mandevilla plant of the Rita Marie Green variety to produce a plurality of plants and selecting at least one double-flowering Mandevilla plant from said plurality of plants. 
     
     
       10. Asexually produced progeny of the double-flowering Mandevilla plant according to claim  1 .
